Aluminum is referred to as a “magical metal.” It’s the third most frequent element in the earth’s crust and the most plentiful metal on the globe, and it’s mostly found as Bauxite ore. What, however, makes it ideal for curtain walls, best windows doors UAE.
The chemical, physical, and mechanical qualities of contemporary aluminium alloys are responsible for the annual increase in global consumption of more than 5%. Here are eight reasons why aluminium frames in the glazing industry are continuing to rise, presently dominating the commercial market and giving UPVC windows UAE run for its money in the residential market.
- Lightweight – Aluminum is a fairly light metal, weighing about 2.7 g/cm3, or approximately a third of the weight of steel or copper. In fact, it’s one of the lightest metals on the market. This makes aluminum perfect for best windows in Dubai and door frames, but when it comes to curtain walling, a lightweight frame is especially vital. Curtain walls aren’t meant to be structural; they can only support their own weight; thus, the lighter they are, the better.
- Resistant to corrosion – If you want a low-maintenance window, aluminium is your best option. This is due to the fact that when aluminium comes into contact with air, a protective layer of forms (aluminium oxide) on the surface almost instantly. This layer is exceptionally resistant to corrosion from the elements, including acid rain, and will not be harmed by cleaning chemicals. Aluminum window frames, unlike timber or PVC-U frames, will not expand, crack, split, or warp with time, regardless of the weather. Anodizing or painting (typically by powder coating) the surface can improve corrosion resistance even more.
- Won’t break – Aluminum is both malleable and ductile, which means it can be bent,pressed into shape, or pulled out into a thin wire without losing its toughness or shattering. To put it another way, it is malleable rather than brittle. Aluminum is, in fact, the second most malleable and sixth most ductile metal. This is great news for anyone looking to create a curved curtain wall or window, since the aluminium frame profiles can be twisted or pressed into the desired shape without breaking.
- 100% Recyclable – When it comes to metal recycling, aluminium is one of a kind. Metal is 100 percent recyclable, and recycled aluminium has the same quality as virgin aluminium. As a result, it can be recycled multiple times. In fact, approximately 75% of all aluminium created in history is still in use today. This is fantastic news for aluminium supply, especially considering that global demand for aluminium has grown to roughly 29 million tonnes per year since the first industrial quantities were produced around 100 years ago. It’s even better news for the environment since, whereas it takes 14,000 kWh to generate 1 tonne of new aluminium, remelting and recycling the same amount only needs 5-10% of that, which means a lower costs.
- Very strong – Window door and curtain wall frames are made of aluminium alloys. This is due to the fact that pure aluminium has a low tensile strength. When aluminum is mixed with other elements such as manganese, silicon, copper, and magnesium, however, its strength skyrockets. The tensile strength of pure aluminium is roughly 90 MPa, but as an alloy, it can reach over 690 MPa. In reality, when utilised as an alloy, aluminium, which is already one of the lightest technical metals, has a significantly greater strength-to-weight ratio than steel. Even more astonishing, unlike steel, aluminum’s strength rises as the temperature drops, whereas steel becomes brittle at low temperatures (below 0oC).
- Easy to make into frames – An extrusion method is used to make aluminium window frames, which involves pressing a pre-heated aluminium alloy through a die to generate an aluminium profile. The frame is then formed by joining these profiles together. The best windows in Dubai frame’s distinct characteristics are due to the design of these profiles. They can be elaborate patterns, but happily, these intricate shapes can be created using a single extruded piece, resulting in robust and durable profiles. Aluminum is also machinable, making it simple to build the aluminium profiles into the finished window frame.
- Decorative – To give metal a decorative smooth or textured appearance, it can be readily anodized or powder coated. As a result, aluminium windows, doors, and curtain walling not only function well but also look great. The aluminium is anodized by immersing it in an acid electrolyte bath and applying an electric current to it. This results in an attractive, long-lasting, corrosion-resistant aluminium oxide coating on the metal surface. Because the aluminium oxide is thoroughly bonded with the underlying aluminium, it will not chip or peel, making it extremely long-lasting. Because aluminium oxide has a porous structure, it must be sealed in order to be corrosion resistant.Anodized metal comes in a variety of hues thanks to the sealant, which might be clear or contain specific dyes. The paint powder is electrostatically charged as it leaves the guns, and the pre-treated aluminium bars are earthed.
